Product Applications
AMSOIL XL Synthetic Motor Oils are excellent for use in all types of gasoline-fueled vehicles. They are recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, the First in Synthetics®, to do the best job protecting your engine.

Extended-Drain Boost Technology
During normal engine operation, the combustion process creates acidic by-products that can lead to internal component corrosion and a reduction in the life expectancy of the engine oil and engine itself. Formulated with extended-drain boost technology, AMSOIL XL Synthetic Motor Oils employ high-quality synthetic base stocks and a unique additive chemistry to neutralize acids longer than conventional oils. The extra additive package effectively raises the Total Base Number (TBN), a measure of an oil’s useful service life, and provides superior protection and performance throughout the entire drain interval.

Bid Appropriate
AMSOIL XL Synthetic Motor Oils fulfill the requirements of most public and private purchasing bids. They are cost effective, making them ideal where synthetic motor oil is specified.

MIXING AMSOIL
AMSOIL XL Synthetic Motor Oils are compatible with conventional and other synthetic motor oils. Mixing AMSOIL XL Synthetic Motor Oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL XL Synthetic Motor Oils.

SERVICE LIFE
In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oils are recommended for up tp 10,000-mile/six-month oil change intervals or longer when recommended in owner's manuals or indicated by electronic oil life monitoring systems. Change aftermarket, original equipment manufacturer or AMSOIL Ea Oil Filter at every oil change.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Not so sure about this product?

I recently switched to this oil in my 4.6L f150. This truck has 106,100 miles on it. It's had motorcraft synthetic blend changed every 3k-5k miles with a fl-820 filter since new. Immediately after switching to this oil the engine developed some cold start and low RPM knocking. I believe this is due to the timing chain tensioners and or guides? The tensioners rely on oil pressure to keep the chains tensioned. So either the motorcraft was hiding a mechanical issue or this 5w20 isn't of similar viscosity to the motorcraft? Oil sample will be sent to blackstone at 3k miles. Still using the motorcraft fl-820 filter with this product. I cannot recommend this product until I have more info.

Full syntetic motor oil.

I have a 2004 Mustang GT and have loved it since the day I got it way back in 2006. Because I plan to keep it, I try to keep it in top shape just like you would... and not cut corners. I go out of my way for the best possible quality in the products I use to keep it looking good but also running even better. It's up in mileage so this is one reason why I switched to a full synthetic oil for the engine. I wasn't familiar with AMSoil but once I was introduced it's all i use now. But like I said earlier, I go out of my way to find the best quality for the price. I've been pleased with this oil more than any other I've used for the past 11 years.

Getting My Friend to Switch to Amsoil

I finally talked my Friend into trying an oil Change to Amsoil. After changing he told me that his truck seemed to be running better, starting much easier, and he thought he was getting better milage. A few days later he told me that now he knew he was getting better milage, about 2mpg. His truck is an older Chevrolet half to 4wd extra cab. I personally was converted a few years ago but thats another story. We can call my friend Brent, He has been building hot rods and high performance motors for years. He wanted one grade higher in weight than was recommended for his truck because of the high miles but now thinks he would have been fine. He is converted and wants to get gear oil and atf so he can change all his fluids to Amsoil products. We will both be changing differentials and transfer case lubricants at the same time.

The 5.7 sees some harsh use during the summer. Towing, extended idling time and dusty roads tend to abuse oil. The Amsoil stands up to the job. Because it is still under warranty I do not exceed the manufacturer recommended service intervals but lab tests show the oil can go well beyond that.

Best all around synthetic engine oil.

I have been using AMSOIL XL 5w20 synthetic engine oil, in my 2007 Dodge Ram 1500 with the 5.7L HEMI, for three years. I have engine conditions from long idle times to full out performance with my performance modified truck. I change my oil & oil filter every 5,000 miles, even though I think this oil would work all the way up to double mileage. The oil still looks very good at that mileage interval. I highly recommend the AMSOIL XL series, it cost less than the top grade synthetic engine oil, works very well in todays modern engines.
